I want to create perspective which shows projects (with all content) with specific tag. I’ve used rule “Tagged with any of” and OF shows only Project titles without any content. Is it possible to create a rule to show everything which is “contained within project with following conditions”?

I want to add tag for the project, then filter by tag and then see this project with all tasks in it.
Note: tasks are without any tags.

Here is my “demo project”: [pic. 1]

And here what I see using filter by tag: [pic. 2]

Here is my perspective filter: [pic. 3]

But I want to see all items within a project with certain tag. Is it possible to do so? I tried to look for filter something like “Has a project which has a tag …”, but didn’t find anything. Are there any workarounds to do this?
